2016 LaCrosse Radio Screen Blank
 

My screen went blank, but my radio works and it I can plug my IPhone in to play music. Screen is just blank. Fuses are good, and I have disconnected the battery. I also tried holding the FF and HOME button...
I'm guessing bad connection behind it. How do I remove system to get behind it? Is it as easy as just removing the bezel around the system? For some reason I think it's more than that...but just not sure? Any thoughts or recommendations?

thanks!
